An international research team, led by Chin - Fei Lee of the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan), has used the Atacama Large Millimeter / submillimeter Array (ALMA) and made two surprising discoveries around
a very young protostar HH212.
This new image not only confirms the formation of an accretion disk around
a very young protostar, but also reveals the vertical structure of the disk for the first time in the earliest phase of star formation.
«In the earliest phase of star formation, there are theoretical difficulties in producing such a disk, because magnetic fields can slow down the rotation of collapsing material, preventing such a disk from forming around
a very young protostar.

Like most dark nebulae, Lupus 3 is an active star formation region, primarily composed of
protostars and
very young stars.
Even
protostars — these are
young stars that are just forming and making their own planetary disks and so on — they make
very powerful outflows called, the same sort of jets obviously moving at slower speeds, but they are full of plasma, that is flowing out at high speed; white dwarfs, neutron stars, black holes big and small, they seem able to do this task, it really seems to be a
very common phenomenon.
The central

very young, with an estimated age of only 40,000 years — about 1/100, 000 th the age of our Sun — and a mass of only 0.2 solar mass.
